The MiniMed Flex system is MiniMed’s latest automated insulin delivery system. It includes a small, screenless insulin pump, SmartGuardTM advanced hybrid closed loop technology, a compatible CGM sensor and infusion set, and the MiniMed™ app so you can control your pump from your compatible device.
You're doing a lot.
A pump can do more.
The MiniMed FlexTM insulin pump system adjusts and corrects sugar levels to protect against highs and lows so you can enjoy more freedom every day.‡
From multiple daily decisions to automatic adjustments
Powered by SmartGuardTM technology, the MiniMed Flex system works day and night to continuously adjust insulin delivery every 5 minutes.‡
Get more support managing insulin throughout the day with automatic insulin adjustments and corrections* every 5 minutes, including support if you miscalculate carbs or occasionally miss a meal dose.§ A 7-day infusion set means changing your infusion set once a week — for up to 96% fewer injections compared with multiple daily injections.*

How do I use the MiniMed Flex pump without a screen?
How do I use the MiniMed Flex pump without a screen?
The MiniMed Flex pump is designed so you don't need a screen. Instead you will use the MiniMed app on your compatible device to view your data and make changes, while the pump will still keep you informed with lights, sounds, and buttons.
How long does the MiniMed Flex pump battery last?
How long does the MiniMed Flex pump battery last?
The pump is charged using a dedicated charging base with a USB-C cable and wall plug, which is included in the pump kit. You can stay connected or disconnect the pump from your body while charging. It’ll take approximately 30 minutes to complete a full charge which should last about 7 days.
You can charge the pump as often as you’d like. Regular charging helps ensure consistent performance.

Is Flex pump waterproof?
The MiniMed Flex pump is waterproof up to 8 feet for 1 hour and 45 minutes (105 minutes).
Can I get the MiniMed Flex if I do not have a compatible smartphone?
Can I get the MiniMed Flex if I do not have a compatible smartphone?
If you don’t have a compatible device, you can purchase App Manager to use the MiniMed Flex System. The App Manager is device that comes with the MiniMedTM app preinstalled and is intended only for managing your diabetes therapy with MiniMedTM systems.
How will the Flex system handle a lost/damaged/out of power phone to continue treatment?
How will the Flex system handle a lost/damaged/out of power phone to continue treatment?
If the pump loses connection to the MiniMed app for whatever reason, it’ll continue to deliver insulin based on what is programmed through the app. Meaning, if you’re in SmartGuardTM mode, it’ll continue to use the SmartGuardTM algorithm, as long as the sensor is still connected to the pump. However, you will need to connect back to the app in order to give a bolus or clear alerts.
It is always recommended to have a back-up plan in place should something happen to your pump or MiniMed app.
Footnotes
‡ Refers to SmartGuardTM feature. Individual results may vary.
§ Taking a bolus 15 – 20 minutes before a meal helps to keep blood sugar levels under control after eating.
◊ Due to inherent real-world study limitations, caution is advised when attempting to extrapolate these results to new patients. There could be significant differences.
¶ Time frame measured is between 12:00 A.M. and 6:00 A.M.
* Assumes 4 injections per day for 30 days and one infusion set change every seven days.

Important Safety Information: MiniMed FlexTM system with SmartGuardTM technology with Simplera SyncTM sensor and Instinct sensor
The MiniMed FlexTM system is intended for the continuous delivery of basal insulin at selectable rates, and the administration of insulin boluses at selectable rates for the management of type 1 diabetes mellitus in persons 7 years of age and older, and of type 2 diabetes mellitus in persons 18 years of age and older requiring insulin. The system is also intended to continuously monitor glucose values in the fluid under the skin.
The MiniMed FlexTM system includes SmartGuardTM technology, which can be programmed to automatically adjust insulin delivery based on continuous glucose monitoring (CGM) sensor glucose values and can suspend delivery of insulin when the SG value falls below or is predicted to fall below predefined threshold values. The system is intended for use with connected sensors, including the Simplera SyncTM sensor and integrated continuous glucose monitors, including the Instinct sensor, each of which has different wear-time, form factor, insertion site, and other distinguishing characteristics that relate to sensor performance. Consult the appropriate sensor user guide when using the system. Discuss treatment decisions with your HCP.
WARNING: Do not use the SmartGuardTM feature for people who require less than 8 units or more than 250 units of total daily insulin per day. A total daily dose of at least 8 units, but no more than 250 units, is required to operate in the SmartGuardTM feature.
WARNING: Do not use the MiniMedTM Flex system until appropriate training has been received from a healthcare professional. Training is essential to ensure the safe use of the MiniMedTM Flex system.
WARNING: Do not use SG values to make treatment decisions, including delivering a bolus, while the pump is in Manual Mode. When the SmartGuardTM feature is active and you are no longer in Manual Mode, the pump uses an SG value, when available, to calculate a bolus amount. However, if your symptoms do not match the SG value, use a blood glucose (BG) meter to confirm the SG value. Failure to confirm glucose levels when your symptoms do not match the SG value can result in the infusion of too much or too little insulin, which may cause hypoglycemia or hyperglycemia.
Pump therapy is not recommended for people whose vision or hearing does not allow for the recognition of pump signals, alerts, or alarms. The safety of the MiniMed FlexTM system has not been studied in pregnant women or in persons using other anti-hyperglycemic therapies that do not include insulin.
